If you are a client of an escort, do not start to plan out your future involving them in anything more than a paid encounter. Do not start talking about settling down, about having a family, about them playing any sort of integral role in your life.
You've found an escort you really like, great, if you want to continue seeing her, keep it professional, you can be friends sure, but you still pay her to have sex with you, do not expects anything more.
It's very rare that the two of you will fall in love and live happily ever after. One in a million.
She is paid to like you, you are probably only seeing a very limited side of her personality, you don't know the whole her, and she will be keeping the not so lovable traits of her personality to herself, my point is you don't know the whole of her, probably you don't even know half of her.
